This invention relates to cooking utensils and more particularly to a means for retaining heat within a cooking utensil, both during the cooking of the articles in the utensil and after the heat has been removed from the utensil.
An object of this invention is to provide a combined insulating jacket and a utensil insertible within the interior of the jacket for holding articles to be cooked, the jacket being of such a construction as to hold the heat about the sides of the utensil during the time that the utensil is disposed over a fire, and including means whereby the heat may be retained about the sides and bottom of the utensil when the fire has been cut oif or when the utensil has been removed from the stove.
The above and various other objects and advantages of this invention will in part be described in, and in part be understood from the following .detail description of the present preferred embodiment, the same being illustrated in the accompanying drawing, wherein:
Figure 1 is a vertical section of an insulating jacket constructed according toI an embodiment of this invention having a cooking utensil, shown in side elevation mounted therein.
Figure 2 is a view similar to Figure 1 but showing the jacket and utensil removed from the stove.
Figure 3 is a fragmentary top plan of the heat retaining jacket.
Referring to the drawing wherein like symbols designate corresponding parts throughout the several views, the numeral IB designates generally an insulated jacket comprising an outer wall II, and an inner wall I2 which is spaced from the outer wall II. Insulating material I3, in the form of asbestos or the like, is interposed between the spaced walls II and I2, so that the jacket I0 retains heat between the inner wall I2 and the wall of a cooking vessel or pan I4. The lower ends of the outer and inner walls II and I2 respectively are flared out, as shown in Figures 1 and 2, and the lower ends thereof are connected A together by a bottom wall I5. The upper ends of the outer and inner walls II and I2 respectively, are connected together by a top wall I6 which is provided with a concave upper surface so as to snugly receive the bead I'I of the pan I4, as will be hereinafter described.
The jacket I0 has a length substantially less than the dep-th of the pan I4 so that when the jacket I0 and the pan I4 are placed on the top of the stove, as shown in Figure l, the rim or bead I1 of the pan I4 will be disposed slightly above the top wall I6 of the jacket I 0 in order to permit the circulation of heated air between the pan I4 and the inner wall of the jacket I0.
The jacket I0 is provided with an outstanding handle 18, which is substantially of the same length as a handle I9 carried by the pan I4. The handle I8 is secured to the jacket I 0 as by rivets or fastening devices 20.
An insulated bottom member 2I is adapted' to receive the jacket I0 and the pan I4 when the fire has been cut 01T- from beneath the pan I4 or when the pan I4 has been removed from the fire. This bottom member 2| comprises a lower plate 22 and an upper or inner plate 23 provided with an enlarged or upwardly offset outer portion 24 terminating in an upwardly extending iiange 25. The outer portion 24 is adapted to receive the bottom I5 of the jacket IIJ, so that when the pan I4 and the jacket I0 are placed on top of the bottom 2|, the bottom of the pan I4 will rest on the inner bottom 23 with the rim I'I snugly engaging the seat I6 of the jacket IIJ. Heat insulating material 26 is interposed between the two bottom members 22 and 23 and may be of asbestos or other suitable heat insulating material.
In the use of this device, when it is desired to cook an article in the pan I4, the article is placed therein and this pan set on top of the stove inside the jacket I0, as shown in Figure 1. The bottom 2i is removed so that the heat can readily contact with the bottom of the pan I4. The heat will rise along the sides of the pan I4 between the sides of the pan and the inner wall I2 of the jacket I [I and then pass out into space between the upper end of the jacket I0 and the rim I'I of the pan I4. After the article or other material has been properly cooked, the pan I4 may be removed from the stove or set to one side on the top thereof, with the pan I4 still retained inside the jacket I0. These two members are then placed on the bottom 2I with the lower end I5 of the jacket I 0 engaging on the seat 24 of the bottom 2i, In this position, the pan i4 is lowered slightly relative to the ,jacket l! so that the rim Il' thereof will snugly engage the concave seat portion I6 on the upper end of the jacket I0. If desired, the pan I4 may have a depth slightly less than the distance between the top wall I6 and the inner bottom wall 23 of the bottom member 2I so that the pan I4 will effectively close the upper end of the jacket It. The heat from the material in the pan i4 will be retained by the heat insulating jacket IU and the heat insulating bottom 2l so that the material in the pan I4 will be kept at a relatively hot temperature for a considerable length of time.
It is, of course, understood that various changes and modications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modications being restricted only by the scope of the following claims.
What is claimed is:-
1. In combination, an annular heat insulating member open at the top and the bottom, a removable bottom for said member provided with a recess in the upper surface thereof, an upstanding ange carried by the bottom and engageable about the lower end of the member, and a vessel engageable within the member and provided with an outstanding rim adapted to rest on the upper edge of the member with the bottom of the Vessel disposed in said recess, said vessel having a depth in excess of the depth of the heat insulating member.
2. In combination, a substantially cylindrical heat insulating member provided with a flared lower end portion, a handle carried by the member, a removable bottom engaging the lower end of the member and provided with a recess in the upper surface thereof, an upstanding flange carried by the bottom and engageable about the lower edge of the member, and a vessel adapted to be disposed within the member and provided with an outstanding rim on the upper edge thereof, said member having a rim seat on the upper edge thereof whereby to snugly receive said rim, said vessel having a depth in excess of the height of the cylindrical member whereby the rim of the vessel Will be disposed in upwardly spaced relation to the upper edge of the cylindrical member when the lower edge of the cylindrical member is resting on a plane surface and the bottom of the Vessel engaging within the recess of the removable bottom when the cylindrical member is resting on the bottom and the rim of the vesselv engages the upper edge of the cylindrical member.
